Description

Technical Field

[0001] This utility model relates to the field of disinfection device technology, specifically a disinfection device for medical devices. Background Technology

[0002] Medical devices refer to instruments, equipment, appliances, in vitro diagnostic reagents and calibrators, materials and other similar or related items that are used directly or indirectly on the human body. After cleaning, medical devices need to be disinfected using a disinfection device.

[0003] Existing medical device sterilization devices typically use high-temperature, high-pressure steam to sterilize medical devices. During use, different types of medical devices are placed inside for sterilization. However, different types of medical devices require different sterilization times. When different types of medical devices are mixed for sterilization, the maximum sterilization time is used. For example, metal instruments that do not need to be stored and are urgently needed require 3-4 minutes of sterilization, while laparoscopic instruments and long catheters require 10-30 minutes. This means that while existing sterilization devices can sterilize, they cannot be categorized and sterilized according to needs. This results in some instruments requiring short sterilization times being sterilized for extended periods, wasting energy and leading to low overall sterilization efficiency and inconvenience. Therefore, we propose a new medical device sterilization device to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a sterilization device for medical devices to solve the problems currently existing in the market as described in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sterilization device for medical devices, comprising a sterilization box, wherein drawer slots are equidistantly arranged on one side of the sterilization box, and a communicating groove is formed inside the other side of the sterilization box, wherein... The connecting groove and the drawer groove are connected through a connecting port. A sealing plug is elastically provided inside the connecting groove corresponding to the connecting port. A drawer is provided in the drawer groove. Ventilation ports are equidistantly opened on the side of the drawer near the connecting port. A top rod is fixedly connected to one end of the drawer corresponding to the connecting port. The drawer is detachably connected to the disinfection box via a quick-release mechanism. The disinfection box has an air inlet pipe connected to the middle of the corresponding connecting groove, and an exhaust pipe connected to the side of the disinfection box near the lower part of the connecting groove. An electric control valve is installed on the exhaust pipe, and a controller is installed on the outer side of the disinfection box near the top.

[0006] Preferably, a bracket is fixedly connected to the inner wall of the connecting slot corresponding to the connecting opening. A spring groove is provided inside the bracket. A guide rod groove is provided at one end of the bracket near the connecting opening. A guide rod passes through the guide rod groove. A baffle is fixedly connected to one end of the guide rod located in the spring groove. A first spring is installed between the baffle and the inner end of the spring groove. A temperature sensor and a pressure sensor are also installed inside the connecting slot.

[0007] Preferably, the push rod is a cylinder, and the outer diameter of the push rod is smaller than the inner diameter of the communication port, and the inner diameter of the communication port is smaller than the outer diameter of the sealing plug, wherein the sealing plug is made of rubber material.

[0008] Preferably, the quick-assembly mechanism includes a transmission wheel groove. The drawer has a transmission wheel groove inside at the end furthest from the top rod. The drawer has symmetrical locking rod grooves on both sides corresponding to the transmission wheel groove. The drawer groove has a locking groove on its inner wall corresponding to the locking rod groove. A locking rod passes through the locking rod groove. A transmission wheel is rotatably connected to the transmission wheel groove. The transmission wheel has symmetrical transmission grooves. A transmission rod is fixedly connected to one side of the locking rod corresponding to the transmission groove. A turntable is fixedly connected to the shaft end of the transmission wheel on the outer side of the drawer. A handle is fixedly connected to the turntable on the side furthest from the drawer. Positioning rod grooves are symmetrically formed on the side of the turntable near the drawer. A groove is formed on the outer side of the drawer corresponding to the positioning rod groove. A second spring is installed in the positioning rod groove. A positioning rod is installed on the opening side of the second spring corresponding to the positioning rod groove.

[0009] Preferably, the end of the positioning rod away from the second spring is a spherical surface, and the outer diameter of the spherical surface of the positioning rod matches the inner diameter of the groove.

[0010] Preferably, a sealing strip is installed on the inner wall of the drawer slot near the opening, and the inner wall of the drawer slot is sealed to the drawer through the sealing strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention introduces high-temperature steam into the connecting slot through an air inlet pipe. When the drawer is installed in the drawer slot, the drawer opens the sealing plug by a top rod, allowing the connecting port to open and the high-temperature steam to enter the drawer through the connecting port and the air vent, thus sterilizing the medical devices inside. When the drawer is pulled out, the connecting port is automatically closed by a spring-loaded sealing plug, allowing the drawer to be pulled out individually. Through multiple sets of drawer slots and drawers, different types of medical devices can be sterilized in a categorized manner.

It allows for more rational use of the sterilization device based on the different sterilization times of different devices, thereby improving the sterilization efficiency of medical devices.

[0012] This invention, when a drawer needs to be installed, causes the handle to rotate the turntable, which in turn rotates the transmission wheel. Simultaneously, when the positioning rod is misaligned with the groove, it is compressed against the second spring force and retracts into the positioning rod groove. As the transmission wheel rotates, it drives the locking rod (which is an arc-shaped groove with one end near the side of the transmission wheel and the other end near the center, facilitating movement of the locking rod) through the transmission groove and transmission rod. After the drawer is inserted into the drawer slot, the turntable is rotated in the opposite direction, causing the locking rod to insert into the locking groove. Simultaneously, the positioning rod aligns with the groove, and the second spring holds the positioning rod against the groove, preventing the lock rod from moving out of the locking groove due to the turntable's automatic rotation. When the drawer needs to be disassembled, the turntable moves the locking rod out of the locking groove, allowing the drawer to be pulled out directly. This quick-assembly and disassembly mechanism enables rapid drawer assembly and disassembly, thereby improving the efficiency of replacing medical devices inside the drawer.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 5 This utility model provides a technical solution: a sterilization device for medical devices, including a sterilization box 1, with drawer slots 2 evenly spaced on one side of the sterilization box 1, and a connecting slot 3 inside the other side of the sterilization box 1, wherein... The connecting groove 3 and the drawer groove 2 are connected through the connecting port 4. The connecting groove 3 is elastically provided with a sealing plug 5 inside the connecting port 4. The drawer groove 2 is provided with a drawer 12. The drawer 12 is provided with vents 13 at equal intervals on the side near the connecting port 4. The drawer 12 is fixedly connected with a top rod 14 at one end corresponding to the connecting port 4. The drawer 12 is detachably connected to the disinfection box 1 via a quick disassembly mechanism. The disinfection box 1 is connected to the middle of the connecting groove 3 via an air inlet pipe 29.

A controller 32 is installed on the outer side of the disinfection box 1 near the top. High-temperature steam is introduced into the connecting groove 3 through the air inlet pipe 29. When the drawer 12 is installed in the drawer groove 2, the drawer 12 opens the sealing plug 5 through the top rod 14, opening the connecting port 4. This allows high-temperature steam to enter the drawer 12 through the connecting port 4 and the air vent 13, disinfecting the medical devices inside the drawer 12. When the drawer 12 is pulled out, the elastically set sealing plug 5 automatically closes the connecting port 4, allowing the drawer 12 to be pulled out individually. By setting multiple sets of drawer grooves 2 and drawers 12, different types of medical devices can be disinfected in a classified manner. Furthermore, when replacing the medical devices in a single drawer 12, it does not affect the normal disinfection of the medical devices in other drawers 12. This allows for more rational use of the disinfection device based on the different disinfection times of different devices, thereby improving the disinfection efficiency of medical devices.

[0017] Please see Figures 1 to 5A bracket 6 is fixedly connected to the inner wall of the connecting groove 3 corresponding to the connecting port 4. A spring groove 7 is opened inside the bracket 6. A guide rod groove 8 is opened at one end of the bracket 6 near the connecting port 4. A guide rod 9 passes through the guide rod groove 8. A baffle 10 is fixedly connected to one end of the guide rod 9 located in the spring groove 7. A first spring 11 is installed between the baffle 10 and the inner end of the spring groove 7. A temperature sensor and a pressure sensor are also installed inside the connecting groove 3. The push rod 14 is a cylinder, and the outer diameter of the push rod 14 is smaller than the inner diameter of the connecting port 4. The inner diameter of the connecting port 4 is smaller than the outer diameter of the sealing plug 5. The sealing plug 5 is made of rubber material. The sealing plug 5 initially... In the current state, the first spring 11 causes the sealing plug 5 to press against the connecting port 4, sealing the connecting port 4. After the drawer 12 is installed, the drawer 12 moves the sealing plug 5 against the elastic force of the first spring 11 through the top rod 14, moving the sealing plug 5 away from the connecting port 4 and opening the connecting port 4, allowing steam to enter the drawer 12 to sterilize the medical device. When the drawer 12 is disassembled, the connecting port 4 can be automatically closed by the sealing plug 5, preventing steam from continuing to enter the drawer slot 2 and causing waste. Through the opening and closing structure of the connecting port 4, the opening and closing of the connecting port 4 can be automatically controlled according to the disassembly and assembly state of the drawer 12.

[0018] Please see Figures 1 to 5The quick-assembly mechanism includes a transmission wheel groove 15. A transmission wheel groove 15 is formed inside the drawer 12 at the end furthest from the top rod 14. Locking rod grooves 16 are symmetrically connected to the upper and lower sides of the transmission wheel groove 15 in the drawer 12. A locking groove 17 is formed on the inner wall of the drawer slot 2 corresponding to the locking rod groove 16. A locking rod 18 passes through the locking rod groove 16. A transmission wheel 19 is rotatably connected inside the transmission wheel groove 15. Transmission grooves 20 are symmetrically formed on the transmission wheel 19. A transmission rod 21 is fixedly connected to one side of the locking rod 18 corresponding to the transmission groove 20. A turntable 22 is fixedly connected to the shaft end of the transmission wheel 19 corresponding to the outer side of the drawer 12. A handle 23 is fixedly connected to the side of the drawer 12 away from the drawer 12. A positioning rod groove 24 is symmetrically formed on the side of the turntable 22 near the drawer 12. A groove 25 is formed on the outer side of the drawer 12 corresponding to the positioning rod groove 24. A second spring 26 is installed inside the positioning rod groove 24. A positioning rod 27 is installed on the opening side of the second spring 26 corresponding to the opening side of the positioning rod groove 24. The end of the positioning rod 27 away from the second spring 26 is spherical, and the outer diameter of the spherical surface of the positioning rod 27 matches the inner diameter of the groove 25. A sealing strip 28 is installed on the inner wall of the drawer groove 2 near the opening. The inner wall of the drawer groove 2 is connected to the drawer 12 through the sealing strip 28. The sealed connection allows the handle 23 to rotate the turntable 22 when drawer 12 needs to be installed. The turntable 22 then rotates the transmission wheel 19. Simultaneously, when the positioning rod 27 is misaligned with the groove 25, the positioning rod 27 is compressed and retracts into the positioning rod groove 24, overcoming the elastic force of the second spring 26. As the transmission wheel 19 rotates, it drives the locking rod 18 to retract into the locking rod groove 16 via the transmission groove 20 and the transmission rod 21. (The transmission groove 20 is an arc-shaped groove, with one end close to the side of the transmission wheel 19 and the other end close to the middle of the transmission wheel 19, thus facilitating the passage of the transmission groove 20 and the transmission rod.) (21 drives the locking rod 18 to move). After the drawer 12 is inserted into the drawer slot 2, the turntable 22 is rotated in the opposite direction to make the locking rod 18 insert into the locking slot 17. At the same time, the positioning rod 27 is aligned with the groove 25. The second spring 26 makes the positioning rod 27 abut against the groove 25 to prevent the turntable 22 from rotating automatically and causing the locking rod 18 to move out of the locking slot 17. When it is necessary to disassemble the drawer 12, the turntable 22 drives the locking rod 18 to move out of the locking slot 17, and the drawer 12 can be pulled out directly. Through this quick disassembly and assembly mechanism, the drawer 12 can be quickly disassembled and assembled, thereby improving the efficiency of replacing medical devices in the drawer 12.

[0019] Working Principle: This medical device sterilization device introduces high-temperature steam into the connecting groove 3 through the air inlet pipe 29. When drawer 12 is installed in drawer groove 2, drawer 12 opens the sealing plug 5 via the top rod 14, opening the connecting port 4. High-temperature steam then enters drawer 12 through the connecting port 4 and the air vent 13, sterilizing the medical devices inside. When drawer 12 is pulled out, the elastically set sealing plug 5 automatically closes the connecting port 4, allowing drawer 12 to be pulled out individually. Through multiple sets of drawer grooves 2 and drawers 12, different types of medical devices can be sterilized separately. Furthermore, replacing medical devices in a single drawer 12 does not affect the normal sterilization of medical devices in other drawers 12. Based on the different disinfection times of different instruments, the disinfection device can be used more rationally to improve the disinfection efficiency of medical instruments. In the initial state, the sealing plug 5 is pressed against the connecting port 4 by the first spring 11 to seal the connecting port 4. After the drawer 12 is installed, the drawer 12 moves the sealing plug 5 against the elastic force of the first spring 11 through the top rod 14, so that the sealing plug 5 moves away from the connecting port 4 and opens the connecting port 4, allowing steam to enter the drawer 12 to disinfect the medical instruments. When the drawer 12 is removed, the connecting port 4 can be automatically closed by the sealing plug 5, which can prevent steam from continuing to enter the drawer slot 2 and causing waste. Through the opening and closing structure of the connecting port 4, the opening and closing of the connecting port 4 can be automatically controlled according to the disassembly and assembly state of the drawer 12. When drawer 12 needs to be installed, handle 23 drives turntable 22 to rotate, turntable 22 drives transmission wheel 19 to rotate, and at the same time, when positioning rod 27 is misaligned with groove 25, positioning rod 27 is squeezed to overcome the elastic force of second spring 26 and retracts into positioning rod groove 24. When transmission wheel 19 rotates, it drives locking rod 18 to retract into locking rod groove 16 through transmission groove 20 and transmission rod 21 (transmission groove 20 is an arc-shaped groove, and one end of transmission groove 20 is close to the side of transmission wheel 19, and the other end of transmission groove 20 is close to the middle of transmission wheel 19, thus facilitating the movement of transmission groove 20 and transmission rod 21). (The locking lever 18 moves) After the drawer 12 is inserted into the drawer slot 2, the turntable 22 is rotated in the opposite direction to insert the locking lever 18 into the locking slot 17. At the same time, the positioning lever 27 is aligned with the groove 25. The second spring 26 makes the positioning lever 27 abut against the groove 25 to prevent the turntable 22 from rotating automatically and causing the locking lever 18 to move out of the locking slot 17. When it is necessary to disassemble the drawer 12, the turntable 22 drives the locking lever 18 to move out of the locking slot 17, and the drawer 12 can be pulled out directly. Through this quick disassembly and assembly mechanism, the drawer 12 can be quickly disassembled and assembled, thereby improving the efficiency of replacing medical devices in the drawer 12.
